IMPROVEMENT IN COMBlNG-MACHINES.

Specification forming part of Letters Patent No. 208,991, dated October15, 1878; application filed September 3, 1878; patented in England,September 14, 1872.

To all whom it may concern:

Be it known that we, THOMAS HENRY RUSH- TON, of the firm of MessienrsDobson & Barlow, of Bolton, in the county of Lancaster, in England,machine-maker, and JAMES MAC- QUEEN, of the. same place, machinist, haveinvented certain new and useful Improvements in Machinery for CombingCotton and other Fibrous Substances; and we hereby declarethe followingto be a full, clear, and exact descripti on thereof, reference being badto the annexed two sheets of drawings, forming part of thisspecification.

Our invention consists in certain improvementsupon the combing-machinesfor which Letters Patent were granted in England to J osu Heilmann onthe 25th day of February, 1846, No. 11,103.

The first part of our invention consists in certain improvedcombinations of machinery forimpartin g the requisite advancing andretrograde motions to the detaching and piecing rollers.

The second part of our invention relates to the nipping apparatus; andit consists in certain improved modes of constructing the said parts, toreduce the cost of construction and the difficulty of adjustment.

On Sheet 1, Figure l is an end view, and Fig. 2 a front view, of ourimproved machinery for imparting the requisite advancin g and retrogrademotions to the detaching and piecing rollers.

a is the cam-shaft, and b the cam, in which is a groove, acting on abowl, 0, which projects from the lever c, to which is cast the toothedsegment d, which gears into the pinion e loose on the axle of thedetaching-roller c. To the shaft a. is also fixed the cam f, which actson a bowl projecting from the levcrf. The toothed segment (1 remains atall times in gear with the pinion c, and a groove is cutin the boss ofthis pinion at 0 and half of a small clutch-box, e is cast to the otherside of the pinion cl. The other half clutch-box, e, is fast to the axleof the detaching-roller e which is placed in close proximity to thecombing-roller, and, in conjunction with the piecing-roller, which islikewise placed close to the said combing-roller and a little above thedetachingroller, returns the fiber to the combing-roller,

to be acted upon again in theirretrograde move ment; but in theiradvance movement they withdraw it from the combing-rollcr and cause itto overlap the other portions previously drawn between them, therebyproducing uniform slivers.

The small cam f works the lever J" from its face, and a swivel-key atthe other end of the lever takes into the groove 6 of the pinion e. Theclutch-box e is put into gear by the spring f and drawn out of gear bythe camf and lever f at the proper times; and, in order to facilitatethe relative amount of advance and retrograde motions, the cam f is madein two parts, as shown in Figs. 3 and 4, the segment f being connectedto the body of the cam f by set-screws passing through slots.

On Sheet 2, Fig. 5 is an end view, and Fig. 6 a front view, of thefeeding-roller and nip ping apparatus of a combing-machine constructedaccording to our improvements. In these views, h is the feeding-roller,which, instead of being placed at some distance from the circumferenceof the combing-cylinder g, as in Heilmanns machines, is brought closeto, but just clear of, the combs on the cylinder. h is the upperfeed-roller. To the nipper-shaft z .are fixed the lifters i throughwhich the setscrews 11 pass. The nipper-plate i is loose on the sameshaft, and it is lined with cloth and leather, or other elasticsubstance, to form a cushion where it acts on the feed-roller h. Thestuds t projecting from the nipper-plate, are acted upon by two spiralsprings, 6 the other end of each spring being connected to the lifters1' On the end of the shaft 11 is fixed a double lever, which is actedupon by a double cam on the shaft g to open and shut the nipper at theproper time. When the cam on the shaft 9 lifts the said double lever onthe shaft 1', and with it the lifters i, which, through the setscrews i,lift the nipper-plate i from the feed roller h, the feedrollers h and hpush the cot ton forward. The nipper is then again acted upon by thesaidcam, double lever, and springs, which bring the plate 11 down on thecotton passing over the feed-roller h, where it is held close to thecombs on the cylinder 9 while it is combed, the feed-roller remainingstationary when the nipper-plate is in contact with it.

This arrangement produces a great reduction in the number of workingparts and facilitates the setting of the nipper. Ihe lapping of thebottom feed-roller and the consequent breaking of the nippenknife leversand the destruction of the cylinder-combs are entirely avoided.

Having thus stated the nature of our invention and described the mannerof performing the same, we declare that What we claim herein as new, anddesire to secure by Letters Patent of the United States, is-

1. The cam-shafta, the cains bf, levers 0')", the toothed segment d, thespring f the slidin g pinion 0, provided with the groove 6 andhalf-clutch e and the stationary half-clutch c, in combination with thedetaching-roller e, substantially as and for the purpose described.

2. The cam f, consisting of two concentric rings, held together by aset-screw, substantially as and for the purpose described.

3. The shaft 17, the nipper-plate i", the lifters t the spring titheset-screw i, the lever 6 the cam g, and comb-cylinder shaft g, incombination with the feed-roller h, substantially as and for the purposedescribed.

In testimony whereof we have hereunto set our hands before twosubscribing witnesses.

THOS. H. RUSHTON. JAMES MAGQUEEN.
